General site characteristics

GyamngönGyam sngon is located in the bottom of an eponymous valley. From the site there is an
expansive view east across the plains of upper ZhidéZhi bde. The views north and west are partly
constrained by higher ground. The view south is blocked by a low-lying ridge on the opposite side of the watercourse. The intermittent stream of the
GyamngönGyam sngon valley runs through a gully immediately south of the monument. The terrain
is level and turf-covered. The site consists of a walled pillar and four outlying funerary structures. The small size of the enclosure with the pillar, the
high elevation of the site and its far northern geographic position suggest that this region was somewhat marginal to the main concentration of archaic
cultural settlement in Upper Tibet. Save for the white pillar, primarily unshaped brown and bluish metamorphic rocks were
used to construct the structures of GyamngönGyam sngon. These rocks probably came from the slopes
south of the site. GyamngönGyam sngon appears to have been heavily impacted by human
activities.

Oral tradition

According to local drokpa’brog pa, GyamngönGyam sngon was an ancient MönMon habitation (dösasdod sa). It is also believed to have emerged with primordial existence as did the MönMon themselves.

Site elements

Enclosure

The enclosure is highly fragmentary and slightly elevated above the surrounding terrain. It measures approximately 6.5 m (east-west) by 3.2 m
(north-south). All fragments are generally aligned in the compass points. There are two stones (20 cm and 40 cm long) fixed around 60 cm from the pillar,
the last remaining vestiges of the west wall of the enclosure. On the east side of what was the north wall there are a few stones in a single line that
appear to be the sole surviving structural component of this enclosure wall. Similarly, on the south side of what was the east wall there are three small
partially buried stones, which appear to be part of the original structure. There are also small stones embedded on what was the south side of the
enclosure, but these exhibit no discernable coherence. Loose stones are scattered around the interior of the enclosure. This contrasts with adjacent
areas, which are mostly free of stones.

Pillar

There is a lone broken tabular white pillar (35 cm [height] by 80 cm [basal girth]). The two broader sides of the pillar face north and south, as is
typical in this monument typology. The pillar is highly eroded and has weathered to an orange brown color in places. It appears to be fairly well centered
between the north and south walls of the enclosure.

Outlying funerary structures

Funerary Structure FS1

Funerary structure FS1 is situated 16 m north of the walled pillar on the opposite side of the motorable track that runs through GyamngönGyam sngon. This highly degraded structure appears to have consisted of both an outer and
inner enclosure. The square inner enclosure (2.5 m by 2.7 m) seems to have been aligned in the cardinal directions. It contains stones that are flush
with the ground surface or slightly elevated above it.

Funerary Structure FS2

Funerary structure FS2 is situated 154 m west-northwest of the walled pillar. This
quadrate funerary enclosure was established on sandy ground, and its walls appear to be aligned in the cardinal directions. FS2 measures approximately
4 m by 5 m. Its north wall (50 cm thick) is the most intact. It is composed of double-course blocks and slabs (15 cm to 40 cm long) set into the
ground edgewise. These stones are level with the ground surface or project above it to a maximum height of 15 cm. The south wall fragment (2.8 m long)
consists of a single line of stones (30 cm to 60 cm long) embedded in the ground, which protrude about 10 cm above ground level. The west wall has
been nearly destroyed. The east wall has only one or two in situ stones remaining. Inside the enclosure there is a single-course slab-wall inner
enclosure, which measures 1.5 m (north-south) by 1 m (east-west). Perhaps marking the location of a burial chamber, the four walls of the inner
enclosure are mostly intact. The north and south walls are composed of smaller stones that project about 10 cm from the ground surface. The east and
west walls are each dominated by a slab about 50 cm in length. This inner enclosure is situated 1.1 m from the inner edge of the south wall of the
outer enclosure, 1.4 m from the north wall, 2.2 m from the east wall, and 1 m from the west wall of the outer enclosure.

Funerary Structure FS3

Funerary structure FS3 is situated 34 m west of the walled pillar. This single-course quadrate enclosure consists of variable-length blocks and slabs
(up to 60 cm long), which are level with the ground surface or which project above it a maximum height of 10 cm. The north wall of FS3 has been
destroyed by the local road. The south wall (5.1 m long) has an east-west axis. The west wall appears to be double-course and has been reduced to 4 m
in length. Some of the west wall was cut by the road. The east wall of the enclosure was almost completely destroyed by the road. The highly
fragmentary south wall appears to be of the double-course variety. Between FS3 and the walled pillar there is a small unused corral, consisting of a
ring of stones. This structure was probably built with stones extracted from the funerary structures.

Funerary Structure FS4

Funerary structure FS4 (4.7 m by 4.2 m) is situated roughly 200 m north of the walled pillar (34.137΄ / 20. 543΄). This quadrate enclosure is highly
deteriorated. It appears to have been aligned in the cardinal directions. The perimeter walls are composed of variable length-blocks and slabs that
project a maximum of 25 cm above ground level. In the north wall there is an insecurely fixed slab 80 cm in length. There also appears to have been an
inner enclosure that is offset towards the west wall of the outer enclosure.
